Title: System and method for editing a structured document to preserve the intended appearance of document elements
Inventor: BORGENDALE KENNETH W
IPC: G06F17/24
Filed: 1991-03-28
Abstract: A data processing system is disclosed for editing a text document stored as at least one alphanumeric string of structured document  text  and displayed  as WYSIWYG text. Look characteristics are controlled for a child document element of the text located within a parent document element of the text. The method performs the step of constructing a child resolved look data set necessary to specify a WYSIWYG appearance of the child element by first accessing modified look value customized by the user for first look parameters and accessing defined look values standardized for second look parameters.  For those look parameters which are not customized by the user or which are not defined as standard values for the child element, the values are inherited by the child element from the parent element.  To do this, the method performs the step of augmenting the child resolved look data set by accessing at least one of the plurality of look values in the parent resolved look data set which does not correspond to the first or the second look parameters. The  resulting  resolved  look  can  completely  specify  the appearance of the child portion of the text when displayed in WYSIWYG form on a display, or when printed in hard copy.

Abstract: A B S T R A C T       Procedure and Device for the Automatic Correction of Skew, of Color Superimposition, and of Image Uniformity for Television Cameras The device for implementation of the invention procedure comprises, first, a processor (2) connected by a data bus (12) to a correction memory (3), a measuring circuit (9), and a digital-to-analog converter (4), and second, to an adder circuit connected to the output of the digital-to-analog converter (45) and to the output of the scanning circuit of the camera so as to add to the sawtooth signal supplied by the camera the correction values furnished by the correction memory in synchrony with the scanning of the camera.  The correction values result from an evaluation of the position error of the centers of the patterns of an optical grid as restored by the camera and of their equivalents in an electronic grid.  Intermediate correction values are computed for each pattern by interpolation of the position errors of the centers of the patterns, using a third-order interpolation polynomial.      Application: High-definition television.

Title: Arrangement for measuring mechanical properties of a foil material
Inventor: PETTERSSON THORULF
IPC: G01N3/02
Filed: 1991-03-21
Abstract: An arrangement for measuring mechanical propert-ies of foil material (10), prefer-ably paper. The arrangement includes a material excitation unit (12) and a material sen-sing detection unit (14). The two units are connected electri-cally to a common arithmetical unit (18). This unit is intended to register and convert electri-cal signals deriving from the two first mentioned units (12, 14) in a manner to produce fi-nal signals which represent the material properties to be mea-sured. The excitation unit (12) includes a laser which, through electromagnetic radiation, is intended to generate in the gaseous atmosphere surround-ing the material local transient gas-pressure pulses within var-iable surface zones which are well-defined geometrically, without the excitation unit coming into contact with the material. These gas pressure pulses cause the material (10) to stretch locally in the boundary regions of the zones, such stretching of the material being necessary to the measur-ing process. The detection unit (14) senses this stretching of the material, without coming into contact with the material, by detec-tingtransient changes in these material zones.

Title: Image transformation on a folded curved surface
Inventor: BROWN DAVID E
IPC: H04N9/74
Filed: 1992-06-08
Abstract: ABSTRACT OF THE DISCLOSURE   A method, system and apparatus is disclosed that performs separable, two-pass image transformations onto folded curved surfaces An image special effects system has an image processing system to receive an input image signal representing an image to be folded and to provide a folded output image signal. A key processing system receives an input key signal to define a portion of the image selected for viewing. It operates in parallel with the image processing system to generate an output key signal which has undergone the same selected spatial transformation relative to the input key signal as did the image. A spatial transformation system operates on the input image signal so as to be able to spatially transform the input image signal on a folded curved surface. The spatial transformation system can be arranged as a separable, two pass transformation process and functions either with h-pass first operations, followed by v-pass operations or with v-pass first operations, followed by h-pass operations. A proportional switcher has two image signal inputs as well as key signal inputs. The proportional switcher generates an output image signal as a combination of image signals received at its image signal inputs in proportion to the key signals. The transformation processing system (a) receives a second image signal and an input key signal defining a region of the second image signal to be included in the output image signal; (b) performs a spatial transformation upon both the second image signal and the input key signal to produce a spatially transformed second image signal and a spatially transformed key signal; (c) provides the transformed second image signal and the transformed key signal to respective inputs of the switcher; and (d) spatially transforms the second image signal by folding the image over itself. The image transformation system separably processes each coordinate direction, for example, it can process the transformation of a horizontal coordinate direction and a vertical coordinate direction, either direction being processed before theother direction. The image transformation system can operate on a signal representing the front view of an image and another signal representing the back view of the image by folding the image to create the special effect of curling an image page in such a manner that parts or all of either its front view and/or its back view become visible.
